Hello everyone,

I have to say that I have next to zero knowledge of DNS. I was looking at my dns manager to setup because I want to set up a subdomain for a forum. I have a few questions.

1. Is this correct:

NS Records

Name Server Subdomain TTL Options

ns1.linode.com http://www.astrocospace.com Default Edit | Remove

if so why is my domain listed under "Subdomain"?

2. I created the forum subdomain per the tutorial I understand that a reverse dns had to be set to it. So I assumed incorrectly that the domain name would be forum.domainname.com when asked for that information to lookup. However that didn't work. So I tried forum.www.domainname.com and that worked. I am now completely confused as to how this works.

3. My SOE Record is as follows:

Domain Settings and Defaults

Domain

http://www.astrocospace.com Example: ns1.domain.com

SOA email

anemail@gmail.com Your email address

Should this be set to astrocospace.com or leave it as is?

4. How do I get my subdomain to work?

This is my site enabled .conf settings:

# The ServerName directive sets the request scheme, hostname and port that

the server uses to identify itself. This is used when creating

redirection URLs. In the context of virtual hosts, the ServerName

specifies what hostname must appear in the request's Host: header to

match this virtual host. For the default virtual host (this file) this

value is not decisive as it is used as a last resort host regardless.

However, you must set it for any further virtual host explicitly.

ServerName http://www.example.com

ServerName astrocospace.com

ServerAdmin webmaster@localhost

ServerAlias http://www.astrocospace.com http://www.astrocospace.com http://astrocospace.com astrocospace.com

DocumentRoot /var/www/html

DirectoryIndex index.html index.php

Available loglevels: trace8, …, trace1, debug, info, notice, warn,

error, crit, alert, emerg.

It is also possible to configure the loglevel for particular

modules, e.g.

LogLevel info ssl:warn

ErrorLog ${APACHELOGDIR}/error.log

CustomLog ${APACHELOGDIR}/access.log combined

For most configuration files from conf-available/, which are

enabled or disabled at a global level, it is possible to

include a line for only one particular virtual host. For example the

following line enables the CGI configuration for this host only

after it has been globally disabled with "a2disconf".

Include conf-available/serve-cgi-bin.conf

ServerName forum.astrocospace.com

DocumentRoot /var/www/forum/

vim: syntax=apache ts=4 sw=4 sts=4 sr noet

I am more than happy to help with any other info you may need and thank you in advance for any and all help received.
